Fiber Optic Cable Opening Tools

Fiber optic cable opening tools, such as mid-span slit and ring tools, are designed to safely access the interior fibers of a cable without damaging the optical fibers inside.

Overview

Fiber optic cable opening tools are essential for technicians who need to access the inner fibers of a cable for splicing, termination, or testing. Unlike copper cables, fiber optic cables require precise handling to avoid signal loss, so specialized tools are used to remove the outer jacket cleanly and safely while preserving the integrity of the fibers inside .

Types of Cable Opening Tools

1. Mid-Span Slit & Ring Tools
   • These tools allow technicians to quickly access interior fibers without cutting the entire cable.
   • Example: Jonard Tools MS-446 Mid Span Slit & Ring Tool, designed for thick-walled cables with diameters from 8.7 mm to 14.6 mm .
   • Ideal for heavy-duty outdoor cables like AFL's OSP MicroCore® series.
2. Cable Jacket Strippers
   • Handheld or thermal strippers remove the outer jacket and buffer coatings.
   • Thermal strippers, such as the TSAB-40, use adjustable heat to remove baked-on coatings and support fiber diameters from 30 µm to 1000 µm .
3. Utility Knives and Precision Cutters
   • Used for smaller or standard cables to slit jackets manually.
   • Often included in fiber optic tool kits for general cable preparation .

Additional Tools for Fiber Preparation

• Fiber Cleavers: Ensure clean, precise cuts for splicing.
• Cleaning Kits: Maintain connector performance and prevent contamination.
• Splicing Tools: Fusion or mechanical splicers for joining fibers with minimal loss .

Considerations for Choosing Tools

• Cable Diameter: Ensure the tool supports the specific cable size.
• Coating Type: Thermal strippers are better for baked-on or thick coatings.
• Durability: Professional-grade tools often come with lifetime warranties and are designed for repeated use in field conditions .
• Safety: Proper tools reduce the risk of fiber damage and signal degradation.
